Abstract

A disk cartridge (20), operable with a disk drive, includes a generally flat-shaped case enclosing a recording medium (38) disposed on a disk (22) about a central hub (40). The case includes top and bottom walls (30,32) disposed on opposite sides of the disk, the bottom wall (32) having an access opening (54) through which a disk drive is to engage with the hub (40). A foil spring (124) has a generally flared dish shape, and is symmetrically formed and positioned about a central axis of the hub (40). The spring (124) is positioned between the disk (22) and the top wall (30) for urging the disk (22) toward the bottom wall (32) to close the access opening (54) with the hub (40) and to close a spindle receiving aperture (48) in the hub (40) to prevent entry of contaminants during periods of nonuse.
